A branch-price-and-cut algorithm for the capacitated multiple vehicle traveling purchaser problem with unitary demand
2021
Abstract The multiple vehicle traveling purchaser problem (MVTPP) consists of simultaneously selecting suppliers and routing a fleet of homogeneous vehicles to purchase different products at the selected suppliers so that all product demands are fulfilled and traveling and purchasing costs are minimized. We consider variants of the MVTPP in which the capacity of the vehicles can become binding and the demand for each product is one unit. Corresponding solution algorithms from the literature are either branch-and-cut or branch-and-price algorithms, where in the latter case the route-generation subproblem is solved on an expanded graph by applying standard dynamic-programming techniques. Our …
The role of the economic crisis on the competitiveness of the agri-food sector in the main Mediterranean countries
2014
Th e world economic crisis that, since 2008 has also struck the real economy, cannot be attributed only to the United States bubble which in 2007 involved the mortgage credit market, but it is the result of a series of factors among which the imbalance of the fi nancial market, of the public accounts of the main economies and the real sector. Also agricul- ture, which has always been considered an anti-cyclic sector, has seen a strong slowdown with a plunge in the trade fl ows. Th is paper analyses the changes which happened to the competitive position in the world market of some Mediterranean countries and of France, Italy, Spain and Turkey in particular trying, moreover, to understand the…
Mayors in the Town Hall: Patterns of Relations and Conflict Among Municipal Actors
2017
The chapter explores the way in which local actors interrelate with each other and the environment surrounding them. For doing so, it analyses the balance of power among municipal actors in European town halls and to what extent these relationships are characterised either by consensus or by conflict. The findings confirm the existence of differences among types of government, confirming the validity of the Mourtizen–Svara’s typology to capture the division of functions at the apex of local leadership forms of local government. When analysing the level of conflict, other factors such as the level of local autonomy in the political system, the municipality’s economic situation or the mayor’s…
Clustering cities through urban metrics analysis
2017
[EN] This paper describes a process for measuring and characterizing urban morphological zones. These urban zones are delineated for the entire area of Spain, independently of administrative boundaries and excluding demographic data, using a high resolution land-use dataset. Given the rich information available on land cover and subsequently assigned population data, it is possible to calculate a set of urban spatial metrics to classify these urban zones into homogenous morphological groups. Four types of urban agglomerations are identified in Spain by working with these urban metrics and applying a final cluster analysis. Although these groups have a general complex monocentric typology, e…

The Impact of Culture and Creativity on the Economy of the City
2019
Abstract Creativity is an important component of the economy for modern cities, and necessary condition for it is the qualitative understanding of the economic theory science. In the global competition, it plays an important role for the economic growth dynamics, which is directly related to human resource role in the modern economy. The competitiveness of the territories depends on their attractiveness to economically active individuals and the opportunities they provide with economic growth. When considering the creative and cultural industries as potential economic development factors in the urban economy, culture can be considered as a new stage in urban development based on quality of …
House prices and proximity to kindergarten – costs of distance and external effects?

Parents accompany children to day-care, implying costs of time and money. Distance to kindergarten may therefore be an important locational attribute, which is likely to be discounted into house pr...
A Gamified Mobility Experience
2020
We believe in the use of urban games to define new enjoyable experiences, change citizens’ unsustainable habits and educate them to new environment-and social-friendly ones. This paper presents MUV, an innovative action that has the power to engage citizens and foster sustainable mobility behaviors. MUV complements engaging HMIs with a participatory method within an iterative innovation process called the virtuous cycle (understand, involve, co-create, implement, experiment). The innovation process has led to a new game dynamic: Mobility as a Sport. It results in a rewarding personal mobility experience; the same rewarding sensations the athletes feel when they improve their results.
